Description

本発明は、気鳴楽器の一種のオカリナに関するものである。   The present invention relates to a kind of scalloped instrument ocarina.

オカリナは一般に、内部に空洞を形成した共鳴胴部と、その共鳴胴部内に空気を吹き込むための吹き口並びにエアウエーと、共鳴胴部に形成されるものであって空気を外部に出す発音源である歌口と、共鳴胴部に穿設される複数個の指孔とから成るものである。オカリナは、複数個の指孔を開閉することによって音程を操作するもので、低いラから1オクターブ高いファまで1オクターブ半の音域を持つものである。   Ocarina is generally a resonance body having a cavity formed inside, a blower opening and an airway for blowing air into the resonance body, and a sound source that is formed in the resonance body and emits air to the outside. It consists of a certain singer and a plurality of finger holes drilled in the resonance body. Ocarina controls the pitch by opening and closing a plurality of finger holes, and has a range of one and a half octaves from low to high one octave higher.

ここで、従来既知のオカリナを図4乃至図8に示す。図4は従来既知のオカリナの平面図、図5は従来既知のオカリナの底面図、図6は従来既知のオカリナの正面図、図7は従来既知のオカリナの裏側部材の水平断面図、図8は図4のA−A線縦断面図である。オカリナ40は、一般的には、型抜きをした表側部材42(図4から見える側の部材…オカリナ40を持った時に上になる部材)と、型抜きをした裏側部材44(図5から見える側の部材…オカリナ40を持った時に下になる部材)とを接合固定して成るものである。   Here, conventionally known ocarinas are shown in FIGS. 4 is a plan view of a known ocarina, FIG. 5 is a bottom view of the ocarina known in the prior art, FIG. 6 is a front view of the ocarina known in the prior art, and FIG. FIG. 5 is a longitudinal sectional view taken along line AA in FIG. 4. In general, the ocarina 40 is a die-cut front side member 42 (a member that can be seen from FIG. 4... A member that is up when the ocarina 40 is held) and a die-backed side member 44 that can be seen from FIG. A member on the side, a member that is placed downward when the ocarina 40 is held, is joined and fixed.

表側部材42には、1個の特定表側指孔46とその特定表側指孔46以外の多数の表側指孔48とが形成される。多数の表側指孔48の中には2個の小孔を有しているが、2個の小孔位置は普遍的なものではない。裏側部材44には、歌口50と第一裏側指孔52と第二裏側指孔54とが形成される。表側部材42と裏側部材44とを接合固定することで共鳴胴部56が形成され、その共鳴胴部56の内部に表側部材42の凹み部と裏側部材44の凹み部とから成る共鳴空間58(図7及び図8参照)が形成される。その共鳴空間58は、特定表側指孔46と多数の表側指孔48と第一裏側指孔52と第二裏側指孔54と歌口50を介して、オカリナ40の外部と通じている。表側部材42と裏側部材44とを接合固定した状態では、一般にはその接合箇所に、共鳴空間58へ空気を吹き込むための吹き口60と、吹き口60と共鳴空間58とを連絡するためのエアウエー62とが形成される(図6及び図7参照)。なお、吹き口60とエアウエー62は、表側部材42と裏側部材44との接合箇所に形成されない場合もある。   The front member 42 is formed with one specific front finger hole 46 and a number of front finger holes 48 other than the specific front finger hole 46. Although many front finger holes 48 have two small holes, the positions of the two small holes are not universal. The back side member 44 is formed with a singing mouth 50, a first back side finger hole 52, and a second back side finger hole 54. A resonance body portion 56 is formed by bonding and fixing the front side member 42 and the back side member 44, and a resonance space 58 (a recess space of the front side member 42 and a recess portion of the back side member 44 is formed inside the resonance body portion 56. 7 and 8) are formed. The resonance space 58 communicates with the outside of the ocarina 40 through the specific front side finger holes 46, a number of front side finger holes 48, the first back side finger holes 52, the second back side finger holes 54, and the singing mouth 50. In a state where the front side member 42 and the back side member 44 are bonded and fixed, generally, the air outlet 60 for injecting air into the resonance space 58 and the airway for connecting the air outlet 60 and the resonance space 58 to the connection portion. 62 (see FIGS. 6 and 7). Note that the blower opening 60 and the airway 62 may not be formed at the joint between the front side member 42 and the back side member 44.

素材を陶器とするオカリナでは、表側部材42と裏側部材44とを接合固定して共鳴胴部56を形成した後、音程や音の響き具合を調整するために、特定表側指孔46と多数の表側指孔48と第一裏側指孔52と第二裏側指孔54と歌口50とエアウエー62等を整形調整し、乾燥後焼成して製品として完成させる。一般的なオカリナの製造方法は、特許文献1に示されている。   In ocarina using ceramics as the material, the front side member 42 and the back side member 44 are joined and fixed to form the resonance body 56, and then the specific front side finger holes 46 and a large number of finger holes 46 are adjusted in order to adjust the pitch and sound reverberation. The front side finger hole 48, the first back side finger hole 52, the second back side finger hole 54, the singing mouth 50, the airway 62, etc. are shaped and adjusted, dried and fired to complete the product. A general method for producing ocarina is disclosed in Patent Document 1.

オカリナによる音程は、ラからドを経て1オクターブ高いドまでを、表側部材42の表側指孔48を開閉することによって作りだす。その後の高い音程であるレは、表側部材42の全部の表側指孔48を開いた状態(特定表側指孔46は閉じた状態)と、裏側部材44の第 一裏側指孔52を開く(第二裏側指孔54は閉じた状態)ことで音を出す。更に高い音程であるミは、表側部材42の全部の表側指孔48を開いた状態(特定表側指孔46は閉じた状態)と、裏側部材44の第一裏側指孔52と第二裏側指孔54を開くことで音を出す。それより高い音程であるファは、表側部材42の全ての表側指孔48と特定表側指孔46とを全部開くと共に、裏側部材44の第一裏側指孔52と第二裏側指孔54とを開くことで音を出す。   The pitch by ocarina is created by opening and closing the front side finger hole 48 of the front side member 42 from la to de through 1 octave higher. After that, the high pitches indicate that the front side finger holes 48 of the front side member 42 are all opened (the specific front side finger holes 46 are closed) and the first back side finger hole 52 of the back side member 44 is opened (first The two back side finger holes 54 are in a closed state). Mi, which has a higher pitch, has a state in which all the front side finger holes 48 of the front side member 42 are opened (a state in which the specific front side finger holes 46 are closed), and a first back side finger hole 52 and a second back side finger of the back side member 44. A sound is produced by opening the hole 54. The fa having a higher pitch opens all the front side finger holes 48 and the specific front side finger holes 46 of the front side member 42 and opens the first back side finger holes 52 and the second back side finger holes 54 of the back side member 44. Sounds when opened.

従来既知のオカリナでは、表側部材42の表側指孔48を開いて、低い方のラからドを経て1オクターブ高いドまでを出す場合には奇麗な音が出るが、裏側部材44の第一裏側指孔52と第二裏側指孔54を開いて、高いレミファ(=高音域)の音を出すと、音の「カスレ」が生じるという不具合が生じることが多かった。この「カスレ」の原因は様々考えられるが、その原因の想定の一例について説明する。高音域の音のレを出す第一裏側指孔52を開いた場合や、高音域の音のミを出す第二裏側指孔54を開いた場合に、開放される空気圧は、歌口50から一番短い距離にあるため、歌口50での発音に影響を与えていると考えられる。一番短い距離を通るということは、第一裏側指孔52や第二裏側指孔54で開放される空気圧が、歌口50から図8でほぼ水平方向に開放されると考えられる。一方、表側部材42の多数の表側指孔48への空気圧は、歌口50から図8でやや垂直方向に開放されると考えられる。水平方向の空気圧の開放の流れとやや垂直方向の空気圧の開放の流れとが歌口50での発音の際に混合し、発音が不安定となって歌口50から出る音がかすれるのではないかと想定される。このため、高音域(高いレミファの音)でのオカリナの演奏は、演奏者にとっても聴衆者にとっても、好ましい音にならなかったという不具合があった。   In the conventionally known ocarina, the front side finger hole 48 of the front side member 42 is opened, and a clean sound is produced when the lower side is passed through the door up to 1 octave higher, but the first back side of the back side member 44 When the finger holes 52 and the second back side finger holes 54 are opened and a high remifa (= high sound range) sound is produced, there is often a problem that sound “scratch” occurs. There are various possible causes of this “smudge”, and an example of an assumption of the cause will be described. When the first back side finger hole 52 for producing a sound in the high frequency range is opened or when the second back side finger hole 54 for producing a sound of the high frequency range is opened, the air pressure to be released is Since it is the shortest distance, it is considered that the pronunciation at the singer 50 is affected. Passing through the shortest distance is considered that the air pressure released by the first back side finger hole 52 and the second back side finger hole 54 is released from the singing mouth 50 in a substantially horizontal direction in FIG. On the other hand, it is considered that the air pressure to the large number of front side finger holes 48 of the front side member 42 is released from the singing mouth 50 in a slightly vertical direction in FIG. The flow of the horizontal air pressure release and the slightly vertical air pressure release flow are mixed when the singing 50 produces sound, and the sound is not stable and the sound coming out of the singing 50 is not blurred. It is assumed. For this reason, there was a problem that the performance of Ocarina in the high sound range (high remifa sound) did not become a favorable sound for both the performer and the audience.

本発明は、上記のような問題点に鑑みて為されたものであり、高音域において音にカスレが生じないオカリナを提供することを目的とする。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an ocarina that does not cause blur in the sound in the high sound range.

上記課題を解決するため、本発明に係るオカリナは、多数の表側指孔を形成した表側部材と、歌口と第一裏側指孔と第二裏側指孔を形成した裏側部材と、前記表側部材と前記裏側部材とを合わせて内部に形成する共鳴空間と、前記共鳴空間に連絡する吹き口及びエアウエーとを有するオカリナにおいて、隔壁を前記裏側部材の内壁に備えることで前記共鳴空間の一部に中央裏側空間部を形成し、前記中央裏側空間部が前記歌口と直接連絡するが前記第一裏側指孔や前記第二裏側指孔と直接連絡しないことを特徴とするものである。本発明は、前記隔壁を、前記歌口と前記第一裏側指孔とを区画する第一隔壁と、前記歌口と前記第二裏側指孔とを区画する第二隔壁とから構成し、前記第一隔壁と前記裏側部材とで前記第一裏側指孔と連絡する第一裏側空間部を形成し、前記第二隔壁と前記裏側部材とで前記第二裏側指孔と連絡する第二裏側空間部を形成し、前記第一隔壁と前記第二隔壁と前記裏側部材とで前記中央裏側空間部を形成し、前記第一裏側指孔を開いた状態では外部に開放される空気圧の流れは第一裏側空間部から前記第一隔壁の自由先端部を乗り越えて前記中央裏側空間部を経由して前記歌口に向かい、前記第二裏側指孔を開いた状態では外部に開放される空気圧の流れは第二裏側空間部から前記第二隔壁の自由先端部を乗り越えて前記中央裏側空間部を介して前記歌口に向かうことを特徴とするものである。本発明は、前記第一隔壁や前記第二隔壁の自由先端部は、前記裏側部材における前記表側部材との接合面とほぼ同一の平面に配置したことを特徴とするものである。   In order to solve the above problems, an ocarina according to the present invention includes a front member formed with a number of front finger holes, a back member formed with a singing mouth, a first back finger hole, and a second back finger hole, and the front member. In the ocarina having a resonance space formed inside and the back side member together, and a blower opening and an airway communicating with the resonance space, a partition wall is provided on the inner wall of the back side member so as to form a part of the resonance space. A central back side space is formed, and the central back side space is in direct communication with the singing lip but is not in direct contact with the first back side finger hole or the second back side finger hole. The present invention comprises the partition comprising a first partition that partitions the singing mouth and the first back side finger hole, and a second partition that partitions the singing mouth and the second back side finger hole, A first back side space that communicates with the first back side finger hole is formed by the first partition and the back side member, and a second back side space that communicates with the second back side finger hole by the second partition and the back side member. The central back side space is formed by the first partition, the second partition, and the back side member, and the air flow that is released to the outside in the state where the first back side finger hole is opened is A flow of air pressure that is released to the outside in a state in which the second back side finger hole is opened from the one back side space part to the singing mouth through the central back side space part over the free tip of the first partition wall. Is over the free front end of the second partition wall from the second back side space and through the center back side space. It is characterized in that toward the mouthpiece. The present invention is characterized in that the free front ends of the first partition and the second partition are arranged on substantially the same plane as the joint surface of the back member with the front member.

本発明に係るオカリナによれば、高音域のレやミやファを出すために第一裏側指孔や第二裏側指孔を開いた場合に、第一裏側指孔や第二裏側指孔と歌口とは、図8で示す水平方向の短距離で連絡するのではなく、隔壁(1つまたは2つの隔壁)によって遮断されている。即ち、第一裏側指孔や第二裏側指孔から歌口に向かう空気圧の開放の流れは、隔壁の自由先端部を乗り越えて、その後、歌口に向かう流れとなる。第一裏側指孔や第二裏側指孔を開いた場合の空気圧の流れは、表側部材の多数の表側指孔を開いた場合の空気圧の流れ(図8で歌口に向けてやや垂直方向に移動する空気圧の流れ)と同じ方向になる。従って、従来既知のオカリナの場合、歌口ではほぼ水平方向とほぼ垂直方向との2つの異なる方向の空気圧の流れが混在することで歌口での空気の振動に干渉をもたらしていたが、本発明では、第一裏側指孔や第二裏側指孔を開いた場合の歌口に向かう空気圧の流れは、隔壁の自由先端部を乗り越えて、ほぼ垂直方向の空気圧の流れとなり、歌口での空気の振動への干渉の発生が低減する。これによって、高音域のレやミやファを出した場合(裏側部材の第一裏側指孔と第二裏側指孔とを開いた場合)に、歌口への空気圧の流れは、同じ方向の流れだけになり、音のカスレの発生を防止することができる。この結果、本発明のオカリナでは、全ての領域で音のカスレが生じない良い音を出すことが可能となる。   According to the ocarina according to the present invention, when the first back side finger hole or the second back side finger hole is opened in order to obtain a high-frequency range, mi or fa, the first back side finger hole or the second back side finger hole and The singing mouth is not connected at a short distance in the horizontal direction shown in FIG. 8, but is blocked by a partition wall (one or two partition walls). That is, the flow of air pressure release from the first back side finger hole or the second back side finger hole to the singing mouth is over the free tip of the partition wall, and then the flow toward the singing mouth. The air pressure flow when the first back side finger hole or the second back side finger hole is opened is the air pressure flow when a number of front side finger holes of the front side member are opened (in FIG. (The direction of the moving air pressure) Therefore, in the case of the conventionally known ocarina, the air pressure flow in two different directions of the singer is mixed in the horizontal direction and the vertical direction, which causes interference with the air vibration in the singer. In the invention, when the first back side finger hole or the second back side finger hole is opened, the flow of air pressure toward the singing mouth overcomes the free tip of the partition wall and becomes a substantially vertical air pressure flow. The occurrence of interference with air vibration is reduced. As a result, the air flow to the singing lip in the same direction when the treble, mis, or fading is released (when the first and second finger holes of the back member are opened). It becomes only a flow, and it is possible to prevent the occurrence of sound blur. As a result, in the ocarina of the present invention, it is possible to produce a good sound that does not cause a sound blur in all areas.

FIG. 2 is a longitudinal sectional view of the ocarina according to the present invention, which corresponds to FIG. The ocarina according to the present invention has the same shape as the plan view of the conventional ocarina shown in FIG. 4, the bottom view of the ocarina shown in FIG. 5, and the front view of the ocarina shown in FIG. The same reference numerals as those in FIGS. 4 to 8 denote the same members in the present invention.

本発明に係わるオカリナ10は、従来既知のオカリナ40と同じ構成要素を備えている。即ち、オカリナ10は、1個の特定表側指孔46と多数の表側指孔48を形成した表側部材42(図4参照)と、歌口50と第一裏側指孔52と第二裏側指孔54とを形成した裏側部材44(図5参照)とを有する。表側部材42と裏側部材44とを接合固定することによって、共鳴胴部56(図7及び図8参照)が形成され、その共鳴胴部56の内部に共鳴空間58(図6及び図7参照)が形成され、更に、その共鳴空間58と連絡する吹き口60とエアウエー62(図1及び図3参照)とが形成される。共鳴空間58は、特定表側指孔46,多数の表側指孔48と、第一裏側指孔52と、第二裏側指孔54と、歌口50と、エアウエー62並びに吹き口60とに連絡する。共鳴空間58は、表側部材42の凹み部である表側空間部12と裏側部材44の凹み部である裏側空間部14とを合わせたもので構成される。   The ocarina 10 according to the present invention includes the same components as the conventionally known ocarina 40. That is, the ocarina 10 includes a front side member 42 (see FIG. 4) in which one specific front side finger hole 46 and a number of front side finger holes 48 are formed, a singer 50, a first back side finger hole 52, and a second back side finger hole. And a back side member 44 (see FIG. 5). By joining and fixing the front side member 42 and the back side member 44, a resonance body portion 56 (see FIGS. 7 and 8) is formed, and a resonance space 58 (see FIGS. 6 and 7) is formed inside the resonance body portion 56. Furthermore, the blower opening 60 and the airway 62 (refer FIG.1 and FIG.3) which connect with the resonance space 58 are formed. The resonance space 58 communicates with the specific front side finger holes 46, a number of front side finger holes 48, the first back side finger holes 52, the second back side finger holes 54, the singing mouth 50, the airway 62 and the air outlet 60. . The resonance space 58 is configured by combining the front side space portion 12 that is a recessed portion of the front side member 42 and the back side space portion 14 that is a recessed portion of the back side member 44.

裏側部材44における裏側空間部14側の内壁面16には、第一裏側指孔52と歌口50とを区画する平面または曲面の板状の第一隔壁18を備えると共に、第二裏側指孔54と歌口50とを区画する平面または曲面の板状の第二隔壁20を備える。これら第一隔壁18と第二隔壁20は、裏側部材44の成型時に裏側部材44に一体に形成しても良いし、成型した裏側部材44の内壁面16にその後取付けるようにしても良い。第一隔壁18や第二隔壁20は、それぞれの両側面と底面が裏側部材44の内壁面16と接合し、その接合面では空気が通過することが無いように設定する。   The inner wall 16 on the back space 14 side of the back member 44 includes a flat or curved plate-shaped first partition wall 18 that partitions the first back finger hole 52 and the singing mouth 50, and a second back finger hole. A flat or curved plate-shaped second partition wall 20 that partitions 54 and the singer 50 is provided. The first partition wall 18 and the second partition wall 20 may be formed integrally with the back side member 44 when the back side member 44 is molded, or may be attached to the inner wall surface 16 of the molded back side member 44 thereafter. The first partition wall 18 and the second partition wall 20 are set so that both side surfaces and the bottom surface thereof are bonded to the inner wall surface 16 of the back member 44, and air does not pass through the bonding surfaces.

図2に示すように、第一隔壁18と第二隔壁20とによって、裏側部材44の裏側空間部14(共鳴空間58の約半分)は、第一裏側空間部22と第二裏側空間部24と中央裏側空間部26との3つの空間部に区画される。第一裏側空間部22は第一裏側指孔52と連絡し、第二裏側空間部24は第二裏側指孔54と連絡し、中央裏側空間部26は歌口50と連絡する。第一隔壁18は、第一裏側空間部22と中央裏側空間部26とを区画する(完全に遮断する)ものであり、具体的には第一裏側指孔52と歌口50との直線的な連絡を遮断するものである。第二隔壁20は、第二裏側空間部24と中央裏側空間部26とを区画する(完全に遮断する)ものであり、具体的には第二裏側指孔54と歌口50との直線的な連絡を遮断するものである。勿論、第一裏側指孔52と第二裏側指孔54とは、第一隔壁18や第二隔壁20によって直接的(直線的)な連絡は遮断されている。   As shown in FIG. 2, the first partition 18 and the second partition 20 allow the back space 14 of the back member 44 (about half of the resonance space 58) to be the first back space 22 and the second back space 24. And the central back side space 26 are divided into three spaces. The first back side space portion 22 communicates with the first back side finger hole 52, the second back side space portion 24 communicates with the second back side finger hole 54, and the central back side space portion 26 communicates with the singer 50. The first partition wall 18 divides (completely blocks) the first back side space portion 22 and the central back side space portion 26, and more specifically, the first back side finger hole 52 and the singing mouth 50 are linear. It is intended to block communication. The second partition 20 divides (completely blocks) the second back side space 24 and the center back side space 26. Specifically, the second partition 20 is linear between the second back side finger hole 54 and the singer 50. It is intended to block communication. Of course, direct communication between the first back side finger hole 52 and the second back side finger hole 54 is blocked by the first partition wall 18 and the second partition wall 20.

この実施例1では、第一隔壁18と第二隔壁20の2つの隔壁によって、歌口50と連絡する中央裏側空間部26を形成する。第一裏側指孔52からの空気圧は、第一裏側空間部22から第一隔壁18の自由先端部28を乗り越えて、表側部材42側の凹み部である表側空間部12を一旦通って、中央裏側空間部26の歌口50に至る。第二裏側指孔54からの空気圧は、第二裏側空間部24から第二隔壁20の自由先端部30を乗り越えて、表側部材42側の凹み部である表側空間部12を一旦通って、中央裏側空間部26の歌口50に至る。   In the first embodiment, the central back side space portion 26 that communicates with the singer 50 is formed by the two partitions, the first partition 18 and the second partition 20. The air pressure from the first back side finger hole 52 passes over the free front end portion 28 of the first partition wall 18 from the first back side space portion 22, and once passes through the front side space portion 12, which is a concave portion on the front side member 42 side. It reaches the singer 50 in the back space 26. The air pressure from the second back side finger hole 54 passes over the free front end portion 30 of the second partition wall 20 from the second back side space portion 24, and once passes through the front side space portion 12, which is a concave portion on the front side member 42 side. It reaches the singer 50 in the back space 26.

第一隔壁18の自由先端部28と第二隔壁20の自由先端部30は、裏側部材44における表側部材42と接合する接合面32と比べてやや高い(図2での裏側部材44における裏側空間部14側を上方向とする)場合であってもやや低い場合であっても良いが、接合面32とほぼ同じ高さ(同一の平面上に配置した)か、やや高い高さとした方がカスレ音が出ない点から望ましい。ほぼ同じ高さ(同一の平面)とは、標準管であるアルトC(横方向の長さは概ね15cm前後)のオカリナの場合には、高さの誤差(約1〜2ミリ)を包含するものとする。なお、オカリナのサイズによっては、高さの誤差が異なってくる。第一隔壁18の自由先端部28と第二隔壁20の自由先端部30が、接合面32の高さよりやや低い場合には、第一裏側空間部22の上側部分と中央裏側空間部26の上側部分とが第一隔壁18の自由先端部28を超えて連絡し、第二裏側空間部24の上側部分と中央裏側空間部26の上側部分とが第二隔壁20の自由先端部30を超えて連絡することになるので、「原則的に」という表現を用いて、第一隔壁18は原則的に第一裏側空間部22と中央裏側空間部26とを区画するとし、第二隔壁20は原則的に第二裏側空間部24と中央裏側空間部26とを区画するとした。   The free front end portion 28 of the first partition wall 18 and the free front end portion 30 of the second partition wall 20 are slightly higher than the joint surface 32 that joins the front side member 42 of the back side member 44 (the back side space of the back side member 44 in FIG. 2). (The portion 14 side is the upper direction) or a slightly lower case, but it is preferable that the joint surface 32 is substantially the same height (arranged on the same plane) or slightly higher. This is desirable from the point that no blur sound is produced. The almost same height (same plane) includes the height error (about 1 to 2 mm) in the case of Ocarina of Alto C (lateral length is about 15 cm) which is the standard tube. Shall. The height error varies depending on the size of the ocarina. When the free tip portion 28 of the first partition wall 18 and the free tip portion 30 of the second partition wall 20 are slightly lower than the height of the joint surface 32, the upper portion of the first back side space portion 22 and the upper side of the center back side space portion 26 are used. And the upper part of the second back side space part 24 and the upper part of the center back side space part 26 exceed the free tip part 30 of the second partition wall 20. Since the first partition 18 is divided into the first back side space 22 and the center back side space 26 in principle using the expression “in principle”, the second partition 20 is in principle. Specifically, the second back side space 24 and the center back side space 26 are defined.

本発明では、高音域のレを出す第一裏側指孔52を開いた場合に、第一裏側空間部22内で開放された空気圧は、その後、第一裏側空間部22から第一隔壁18の自由先端部28を乗り越えて(表側部材42の表側空間部12に一旦入って)中央裏側空間部26に至り、その後、歌口50で振動することで音が鳴る。同様に、高音域のミを出す第二裏側指孔54を開いた場合にも、第二裏側空間部24内で開放された空気圧は、その後、第二裏側空間部24から第二隔壁20の自由先端部30を乗り越えて(表側部材42の表側空間部12に一旦入って)中央裏側空間部26に至り、その後、歌口50で振動することで音が鳴る。   In the present invention, when the first back side finger hole 52 that emits a treble range is opened, the air pressure released in the first back side space 22 is then transferred from the first back side space 22 to the first partition wall 18. A sound is produced by getting over the free front end portion 28 (once entering the front side space portion 12 of the front side member 42) and reaching the center back side space portion 26, and then vibrating at the singing mouth 50. Similarly, even when the second back side finger hole 54 that emits a high-frequency sound is opened, the air pressure released in the second back side space part 24 is then transferred from the second back side space part 24 to the second partition wall 20. Overcoming the free tip 30 (entering the front space 12 of the front member 42 once) reaches the center back space 26 and then vibrates at the singer 50 to make a sound.

以上のように本発明では、裏側部材44における裏側空間部14(共鳴空間58の約半分)において、第一裏側指孔52と歌口50とは第一隔壁18で遮断されているので、第一裏側指孔52から歌口50へ向かう空気圧は、第一隔壁18の自由先端部28を乗り越えてから中央裏側空間部26を経て歌口50に向かうように設定される。即ち、第一裏側指孔52から歌口50へ向かう空気圧の流れは、表側部材42の多数の表側指孔48から歌口50へ向かう空気圧の流れとほぼ同じ方向の流れとなる。同様に、第二裏側指孔54と歌口50とは第二隔壁20で遮断され、第二裏側指孔54から歌口50へ向かう空気圧は、第二隔壁20の自由先端部30を乗り越えてから中央裏側空間部26を経て歌口50に向かうように設定される。即ち、第二裏側指孔54から歌口50へ向かう空気圧の流れは、表側部材42の多数の表側指孔48から歌口50へ向かう空気圧の流れとほぼ同じ方向の流れとなる。   As described above, according to the present invention, the first back side finger hole 52 and the singing mouth 50 are blocked by the first partition wall 18 in the back side space portion 14 (about half of the resonance space 58) of the back side member 44. The air pressure from the one-side finger hole 52 toward the singing mouth 50 is set so as to go over the free tip 28 of the first partition wall 18 and then toward the singing mouth 50 through the central back-side space portion 26. In other words, the flow of air pressure from the first back side finger hole 52 to the singing mouth 50 is substantially the same direction as the flow of air pressure from the front side finger holes 48 of the front side member 42 to the singing mouth 50. Similarly, the second back side finger hole 54 and the singing mouth 50 are blocked by the second partition wall 20, and the air pressure from the second back side finger hole 54 to the singing mouth 50 gets over the free tip 30 of the second partition wall 20. To the singing mouth 50 through the central back side space 26. That is, the flow of air pressure from the second back side finger hole 54 to the singing mouth 50 is in the same direction as the flow of air pressure from the front side finger holes 48 of the front side member 42 to the singing mouth 50.

従来のオカリナでは、高音域のレを出す第一裏側指孔52を開いた場合や、高音域のミを出す第二裏側指孔54を開いた場合に、そこで開放された空気圧は、何も遮られるものが無いために、水平方向に歌口50に移動する(図6参照)。この水平方向の空気圧の流れと、表側部材42の多数の表側指孔48からの歌口50に向かうほぼ垂直方向の空気圧の流れ(図6参照)とが歌口50で混ざり合って、それらの異なる空気の圧力が歌口50の発音に干渉して、カスレ音が出ると想定される。これに対して、本発明では、高音域のレを出す第一裏側指孔52を開いた場合や、高音域のミを出す第二裏側指孔54を開いた場合に、開放された空気は、第一隔壁18や第二隔壁20を乗り越えて中央裏側空間部26に入り、その後歌口50に向かう。この歌口50に向かう空気圧の流れは、表側部材42の多数の表側指孔48からの歌口50に向かう空気圧の流れとほぼ同じ流れとなる。これによって、歌口50での異なった空気の圧力による混合の発生がないため、カスレが生じることがないと想定される。よって、本発明では、高音域のレやミを出すために裏側指孔52,54を開いた場合に、音のカスレを生じることがなく、全ての良好な音を出すことができる。
なお、中央裏側空間部26はある程度の広い空間の確保が望ましく、第一隔壁18と第二隔壁20の2つの隔壁を用いることで中央裏側空間部26を簡単により広く形成することが可能となる。
In the conventional ocarina, when the first back side finger hole 52 for producing a high frequency range is opened or when the second back side finger hole 54 for producing a high range sound is opened, the air pressure released there is nothing. Since there is nothing obstructed, it moves to the singer 50 in the horizontal direction (see FIG. 6). The horizontal air flow and the substantially vertical air flow (see FIG. 6) from the front finger holes 48 of the front member 42 toward the singing mouth 50 are mixed in the singing mouth 50, It is assumed that a different air pressure interferes with the pronunciation of the singer 50 and produces a ding sound. On the other hand, in the present invention, when the first back side finger hole 52 that emits a treble range is opened, or when the second back side finger hole 54 that produces a treble range is opened, the released air is , Over the first partition wall 18 and the second partition wall 20, enter the center back side space portion 26, and then head to the singing mouth 50. The flow of air pressure toward the singing mouth 50 is substantially the same as the flow of air pressure toward the singing mouth 50 from the large number of front side finger holes 48 of the front side member 42. As a result, there is no mixing due to different air pressures at the singer 50, so it is assumed that no blurring occurs. Therefore, in the present invention, when the back-side finger holes 52 and 54 are opened in order to produce a high-frequency range, the sound is not blurred, and all good sounds can be produced.
Note that it is desirable to secure a certain amount of wide space for the center back side space portion 26, and by using two partitions, the first partition wall 18 and the second partition wall 20, the center back side space portion 26 can be easily and widely formed. .

次に、本発明の実施例2を図3に基づいて説明する。実施例1(図1や図2)では、第一隔壁18と第二隔壁20の2つの隔壁によって、歌口50を囲む中央裏側空間部26を形成する。第一隔壁18によって中央裏側空間部26と第一裏側指孔52とを区画し、第二隔壁20によって中央裏側空間部26と第二裏側指孔54とを区画し、2つの隔壁18,20によって第一裏側指孔52とを第二裏側指孔54とを区画した。これに対して、図3に示す実施例2では、例えば曲面状で板状の1つの隔壁34によって、裏側空間部14を、歌口50と連絡する中央裏側空間部38と、第一裏側指孔52や第二裏側指孔54と連絡する裏側空間部36とに区画する。隔壁34では、その両側面と底面が裏側部材44の内壁面16と接合し、その接合面では空気が通過することが無いように設定する。この実施例2では、第一裏側指孔52や第二裏側指孔54が開放された場合の空気圧は、隔壁34の自由先端部を通って、表側部材42側の凹み部である表側空間部12を一旦通って、中央裏側空間部38に連絡するが、歌口50(中央裏側空間部38)と第一裏側指孔52や第二裏側指孔54とは直接連絡しないようにするものである。   Next, a second embodiment of the present invention will be described with reference to FIG. In Example 1 (FIG. 1 and FIG. 2), the center back side space part 26 which surrounds the singing mouth 50 is formed by the two partition walls of the first partition wall 18 and the second partition wall 20. The central partition side space 26 and the first back side finger hole 52 are partitioned by the first partition wall 18, and the center back side space part 26 and the second back side finger hole 54 are partitioned by the second partition wall 20, and the two partition walls 18, 20 are separated. Thus, the first back side finger hole 52 and the second back side finger hole 54 were partitioned. On the other hand, in Example 2 shown in FIG. 3, for example, by a curved and plate-shaped partition wall 34, the back space 14 is connected to the center back space 38 that communicates with the singer 50, and the first back finger. A back space 36 that communicates with the holes 52 and the second back finger holes 54 is partitioned. The partition wall 34 is set so that both side surfaces and the bottom surface thereof are joined to the inner wall surface 16 of the back member 44 and air does not pass through the joining surface. In the second embodiment, the air pressure when the first back side finger hole 52 and the second back side finger hole 54 are opened passes through the free tip portion of the partition wall 34 and is a front side space portion that is a concave portion on the front side member 42 side. 12 is connected to the center back side space 38, but the singing mouth 50 (center back side space 38) is not directly connected to the first back side finger hole 52 and the second back side finger hole 54. is there.

以上のように実施例2においても、裏側空間部14(共鳴空間58の約半分)において、第一裏側指孔52や第二裏側指孔54と歌口50とは隔壁34で遮断されているので、第一裏側指孔52や第二裏側指孔54から歌口50へ向かう空気圧は、隔壁34の自由先端部を乗り越えてから中央裏側空間部38を経て歌口50に向かうように設定される。即ち、第一裏側指孔52や第二裏側指孔54から歌口50へ向かう空気圧の流れは、表側部材42の多数の表側指孔48から歌口50へ向かう空気圧の流れとほぼ同じ方向の流れとなる。よって、歌口50での異なった空気の圧力による混合の発生がなくなり、カスレが生じることがないと想定される。よって、本発明では、高音域のレやミを出すために裏側指孔52,54を開いた場合に、音のカスレを生じることがなく、全ての良好な音を出すことができる。   As described above, also in the second embodiment, the first back side finger hole 52, the second back side finger hole 54, and the singing mouth 50 are blocked by the partition wall 34 in the back side space portion 14 (about half of the resonance space 58). Therefore, the air pressure from the first back side finger hole 52 or the second back side finger hole 54 toward the singing mouth 50 is set so as to go over the free tip of the partition wall 34 and then toward the singing mouth 50 through the central back side space 38. The That is, the flow of air pressure from the first back side finger hole 52 or the second back side finger hole 54 to the singing mouth 50 is in the same direction as the flow of air pressure from the many front side finger holes 48 of the front side member 42 to the singing mouth 50. It becomes a flow. Therefore, it is assumed that no mixing occurs due to different air pressures at the singer 50 and no blurring occurs. Therefore, in the present invention, when the back-side finger holes 52 and 54 are opened in order to produce a high-frequency range, the sound is not blurred, and all good sounds can be produced.
